Discovered in 1933 and classified in the 1960s as a prototype for the arena virus, lymphocytic choriomeningitis virus (LCMV) is harbored in mice and transferred vertically by uterine infection.
In late 2008, for example, the system was used to discover a new zoonotic arena virus responsible for a highly fatal hemorrhagic fever outbreak in South Africa.
